How to use the online alarm clock
Preparing the henhouse before it needs securing makes the 7:00 pm alarm a useful boundary for the evening. The latch can be checked, a torch left by the back door and anything blocking the path moved while there is still daylight. When the alarm sounds, the hens can be shut in before urban foxes begin exploring gardens and allotments.
Because the henhouse routine is being arranged ahead of time, leave this alarm page visible while setting out what you need. A page moved into the background normally stays loaded, although the browser may reduce its activity and delay sound, particularly when power-saving settings intervene. This browser alarm cannot protect the henhouse if its session has ended or the sleeping phone is no longer running it, so a separate phone alarm is sensible when missing 7:00 pm would leave the birds outside.
Once the hens are settled, supper can follow without interrupting the trip outdoors. Beforehand, a glass of water or a small snack is easier to fit around gathering feed and checking the latch than a full evening meal. Hot food and a longer drink can wait until after 7:00 pm, avoiding a cooling plate indoors or a rushed final check at the henhouse.
Common questions
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
